Catalyst Grade Antimony Trioxide

    NNN® Catalyst Antimony Trioxide is specially designed as catalysts for many PET polymerization processes.  The product is of very consistent quality and high reactivity and solubility in ethylene glycol.  It is very white and pure, and its particle size is small and particle size distribution is very tight.

    NNN® Catalyst Antimony Trioxide is manufactured from high purity electrolytic antimony metal, which is made by the electrowinning process. 

NNN® Catalyst Antimony Trioxide is packed in 25 kg paper bags, 1000 kg super sacks.  Custom packaging is available upon request.

NNN® Catalyst Antimony Trioxide is also available in a form wetted with ethylene glycol.
